This report describes some preliminary attributes of stimuli developed for future evaluation of nonverbal emotion in neurological populations with acquired communication impairments. Facial and vocal exemplars of six target emotions were elicited from four male and four female encoders and then prejudged by 10 young decoders to establish the category membership of each item at an acceptable con...

Is processing of conceptual information as robust as processing of perceptual information early in development? Existing empirical evidence is insufficient to answer this question. To examine this issue, 3- to 5-year-old children were presented with a flexible categorization task, in which target items (e.g., an open red umbrella) shared category membership with one test item (e.g., a folded um...

We studied the role of action in a conceptual combination task by varying whether word stimuli could be physically grasped and arranged (words displayed individually on tangible cubes) or only touched and pointed to (words printed on a poster paper). Middle-school aged participants combined nouns from different taxonomic categories then described creative meanings. Descriptions contained more b...

This kind of category ambiguity has been cited as evidence against the logical possibility of learning grammatical categories from distribution (Pinker 1987). Indeed, if we are to take seriously the many proposals that children may learn which words should be categorized together based on such cues as local co-occurrence (e.g., Redington, Chater & Finch 1998; Mintz 2003), we must address the po...

We study the splitting of the Goodwillie towers of functors in various settings. In particular, we produce splitting criteria for functors F : A → MA from a pointed category with coproducts to A-modules in terms of differentials of F . Here A is a commutative S-algebra. We specialize to the case when A is the category of a-algebras for an operad a and F is the forgetful functor, and derive mild...

We introduce a relativized notion of (semi)normalcy for categories that come equipped with a proper stable factorization system, and we use radicals and normal closure operators in order to study torsion theories in such categories. Our results generalize and complement recent studies in the realm of semi-abelian and, in part, homological categories. In particular, we characterize both, torsion...

A trivalent diagram is a connected graph with cyclic orientations and degree conditions on its vertices. It is the combinatorial description of an unembedded trivalent ribbon graph. We shall describe and analyze an algorithm giving an exhaustive list of trivalent diagrams of a given size. The list being nonredundant in that no two diagrams of the list are isomorphic. The algorithm will be shown...

One approach to deal with real complex systems is to use two or more techniques in order to combine their different strengths and overcome each other’s weakness to generate hybrid solutions. In this project we pointed out the needs of an improved system in toxicology prediction. An architecture able to satisfy these needs has been developed. The main tools we integrated are rules and ANN. We de...

This paper gives analogies of Hutton’s quasi-uniformities for complete lattices and extensions of Shi’s pointwise quasi-uniformities to closed set lattices.CLGOH denotes the category of all complete lattices with generalized order homomorphisms asmorphisms and CSL the category of all closed set lattices.HQUnif and SPQUnif denote the categories of Hutton quasi-uniform spaces on complete lattices...

To elucidate the role of thrombocytosis, alone or in combination with standard (age, previous cardiovascular events) and novel (leukocytosis, JAK2(V617F) mutational status) risk factors, in the cardiovascular events of essential thrombocythemia (ET), we analyzed a cohort of 1063 patients. We found that a platelet count at diagnosis greater than 1000 x 10(9)/L was associated with significantly l...
